Abstract
The present invention relates to a method of adding Mg in the production process of a magaluma ingot and is characterized in that the production process is when the aluminium ingot is melted and flows into a rest finery through a launder, the needed Mg is added at the launder. The method is that the needed magaluma ingot is put into a converter launder ingot after ingot in the mode of breaking up the whole into parts and let the high temperature flowing aluminium fluid rinse and melt the magaluma ingot, achieving the alloying of Mg and Al in the process of rinsing and melting, thereby achieving the goals of reducing the loss of Mg, increasing the casting yield of Mg, controlling the component content of Mg accurately. The present invention is of a notable economic effect.
Description
Technical field
The present invention relates to add in a kind of aluminum magnesium alloy ingot production process the method for magnesium.
Background technology
At present nearly all aluminum magnesium alloy ingot manufacturing enterprise all adopts a kind of like this method to adjust control Mg content when producing the aluminum magnesium alloy ingot---and in holding furnace, concentrate and add the Mg ingot and then spread insulating covering agent.Because the proportion of Mg is lighter than Al, fusing point is lower than aluminium, the Mg ingot will float on the pyritous liquid aluminum after adding holding furnace, contacts with air oxidizing fire reaction (2Mg+O takes place
2=2MgO), so adopt this method, the scaling loss of Mg is very big, usually can be up to 20%-25%, and optimum level is also about 15%; And under this operational method, workpeople's activity duration prolongs, and labour intensity increases, and operating environment is tending towards badly, and labour productivity is low, and production cost is higher.
Find the addition means of suitable Mg ingot, reduce the scaling loss of Mg, the casting yield of raising Mg, the component content of control Mg has become the nerve-racking agricultural technology problem of extremely having a headache.
Summary of the invention
The objective of the invention is deficiency at above-mentioned prior art existence, provide a kind of and can effectively solve the higher problem of scaling loss that contains Mg in the Mg aluminum alloy ingot blending process, improve the casting yield of Mg, accurately control the method for adding magnesium in the aluminum magnesium alloy ingot production process of component content of Mg.
The objective of the invention is to be achieved through the following technical solutions.
Add the method for magnesium in a kind of aluminum magnesium alloy ingot production process, it is characterized in that production process is to enter when leaving standstill refining furnace by chute in aluminium ingot fusing back, adds the magnesium of required adding at the chute place.
Method of the present invention, the adding of magnesium can gradation add gradually., by the mode that breaks the whole up into parts, the Mg ingot bar that needs are added is placed in the converter chute, allows the aluminium liquid of temperature flowing remove to dash molten Mg ingot, realizes the alloying process of Mg and Al in dashing molten process, and converter finishes and spreads insulating covering agent again.
Method of the present invention, easy and simple to handle, not only accelerate the alloying process of Mg and Al, and shortened the batching time, improved the accuracy of labour productivity and batching.The scaling loss of Mg drops to about 5% from comparatively general 20%-25%, and casting yield increases substantially, and technique effect is obvious.Reduced the consumption of magnesium ingot and insulating covering agent, reduced production cost, economical effectiveness is obvious.Reduce the consumption of insulating covering agent, improved the operating environment of having optimized the workpeople, alleviated labour intensity.
Embodiment
Add the method for magnesium in a kind of aluminum magnesium alloy ingot production process, production process is to enter when leaving standstill refining furnace by chute in aluminium ingot fusing back, adds the magnesium of required adding at the chute place.
Embodiment
Aluminium liquid in smelting furnace through batching, skim after, import by the converter chute and to leave standstill in the stove, in accordance with regulations addition is placed on Mg ingot block-by-block dash in the converter chute and melts during converter.Treat aluminium liquid enter fully leave standstill stove after, " purifier " that is connected with refining gas and refining agent inserted in the furnace charge refining 30 minutes, scratch clean the thin slag of liquid level once more, measure temperature in the processing requirement scope, leave standstill after 40 minutes and change casting over to.During casting, the graphite rotator that is connected with refining gas in the degasification tank produces a large amount of dispersivity bubbles in the high speed rotating process, these bubbles are taken gas in the aluminium liquid and thin slag out of in floating-upward process, when flowing through strumbox through the aluminium liquid of degasification, slagging-off, the ceramic plate in the strumbox carries out once more purification filtering to aluminium liquid.At last, the aluminium liquid after purifying treatment enters crystallizer through movable chute, crystallized into by cooling and is ingot casting.The burn out rate of Mg is 5%, and casting yield increases substantially, and technique effect is obvious.
Claims (1)
1. add the method for magnesium in the aluminum magnesium alloy ingot production process, it is characterized in that production process is to enter when leaving standstill refining furnace by chute in aluminium ingot fusing back, adds the magnesium of required adding at the chute place.
